* lib-src/emacsclient.c (getenv): Remove decl.
* lib-src/make-docfile.c (write_globals): Add ATTRIBUTE_CONST for
Fbyteorder, Ftool_bar_height, Fmax_char, Fidentity.
* lwlib/lwlib-Xm.c (lw_motif_widget_p, xm_update_one_value)
(xm_create_dialog, xm_destroy_instance, xm_popup_menu)
(xm_set_keyboard_focus, xm_set_main_areas): Remove decls.

(x_set_menu_bar_lines):
* src/ftfont.c (ftfont_font_format):
* src/intervals.h (Qkeymap, Qfont):
* src/keyboard.c (timer_check, safe_run_hooks, Qregion_extract_function):
* src/lisp.h (Ffboundp, Qnil, Qt, Qlambda, Qintegerp, Qwholenump)
(Qsymbolp, Qlisp, Qconsp, Qstringp, Qarrayp, Qbufferp, Qmarkerp)
(Qvectorp, Qbuffer_or_string_p, Qchar_table_p, Qvector_or_char_table_p)
(Qfloatp, Qnumberp, Qfont_spec, Qfont_entity, Qfont_object)
